- Implemented a custom tracing layer (`AppLogLayer`) to capture log events and broadcast them to SSE clients. - Created admin routes for streaming server logs and listing recent activity logs. - Added an activity log repository interface and SQLite implementation for persisting activity events. - Integrated activity logging into user authentication and channel CRUD operations. - Developed frontend components for displaying server logs and activity logs in the admin panel. - Enhanced the video player with a stats overlay for monitoring streaming metrics.
